It's more complicated than that.
Class organizers publish a fee for members and non-members. From that, KCBS collects a check covering the course fees, member fees for non-members, and the cost of meat, cooking supplies, and non-cooking supplies.
The cook is then paid for their supplies by KCBS. The cook may also be reimbursed for their cooking services and travel by the organizer.
The organizers then pays the KCBS reps directly for any travel expenses incurred.
Overly complicated? :becky: Sure. I think they do it this way so they control what supplies are used in the class. Meat purchases are VERY limited, so you aren't going to get comp style food in a judging class.
KCBS also tells organizers that the classes are not to be considered money making ventures. Of course the organizers bear the risk - there is a minimum charge for the class, and the reps will have travel expenses whether the class sells out or not, so organizers will try to make some profit on classes. It's generally not much though, and sometimes the classes lose money (for the organizers, not KCBS.)
